Latency is a key issue in these international callback systems. I recommended Celtrek service to a friend as being cheaper than using a Japanese prepaid in Japan. It was. It worked just fine. His wife refused to talk on the phone because she could not get used to the latency. When talking to her relatives in Japan, while in Japan, the call had to go around the world and back again. This introduced such a delay she couldn't accomodate to it. (Most people don't have a half-duplex mode.) Had they been roaming normally, the delay wouldn't have been an issue.
